Claims priority, application Switaerland October 29, 1949 14 Claims.

The present invention relates to spinning machines and, particularly, to slubbing, roving, spinning, or twisting frames with vertically reciprocable parts.

With some types of spinning machines, particularly ring spinning and ring twisting frames, the building up of the bobbin is accomplishedin a constant up and down motion. To this end, mainly the spindle or ring rails are moved up and down, either individually or together, but the drawing frames, thread guides and antiballooning devicesdepending on the type of machine-are also moved in vertical or nearly vertical direction.

In most of the machines of this kind, the vertically moved parts form separate aggregates with individual drives for the up and down motion which are guided on the machine frame by means of special slide or guide rods or bars. For example, there are ring spinning frames in which the ring rail is guided along a column or guideway, while its up and down motion is derived from a gear system which is located at the machine frame outside the guiding device and which transmits the movement through chains or belts, racks or similar transmission means.

Such a separation of the guiding means from the motion of the vertically movable parts is disadvantageous in so far as it renders the design of the machine unnecessarily intricate and makes the operation and maintenance more diflicult. In addition thereto, it gives rise to inconvenient accumulations of dust while requiring increased power due to the inevitable transverse force components caused by the lever effect. a

It is an object of the present invention to provide a simplified spinning machine which will overcome the above mentioned drawbacks.

It is another object of this invention to provide an improved spinning machine construction which includes a plurality of vertically reciprocable parts arranged in vertically spaced relationship and having one and the same member in common as part of the operating mechanism for effecting the reciprocating movement of said vertically reciprocable parts.

It is still another object of this invention to provide a spinning machine construction of the type set forth in the preceding paragraph which will make it possible to move the vertically reciprocable parts up and down at different speeds with regard to each other.

These and other objects and advantages of the invention will appear more clearly from the following specification ,in connection with the accompanying drawings in which:

, sectional views of machine frames including shaft or column constructions according to this invention.

Fig. 4 is a diagrammatic transverse sectional view of a different type of machine frame having shafts or columns in accordance with the invention.

Fig. 5 is a diagrammatic plan view representing a section through the machine frame shown in Fig. 4.

Fig. 5a is a side view of a portion of Fig. 5.

General arrangement I According to the present invention, the axis of the guiding means for the vertically reciprocable parts coincides with the axis of a member of the actuating mechanism for the reciprocal movement of said parts. Due to this co-axial arrangement of the guiding means and motion, all transverse force components are eliminated, and the machine is made simple and clear.

More specifically, according to the present invention, the vertically reciprocable parts are guided along a vertical shaft or column which forms part of the lifting and lowering mecha-. nism. It is to be understood that the shaft or column may be designed as screw spindle operating in conjunction with at least one vertically movable nut. The shaft or column may also be designed as piston rod having at least one piston connected thereto for cooperation with a reciprocable cylinder.

It is particularly advantageous to use the column or shaft as a support for the machine frame as is suggested by the present invention. Thus, special machine uprights are not required.

This idea of the invention can be realized in various ways. According to one embodiment of the invention, two shafts or columns arranged in a transverse plane of the machine are connected to each other by means of transverse members which latter are connected by means of longitudinal members to similar transverse members of adjacent shafts or columns.

Another form of embodiment is characterized by a single line of vertical shafts or columns which are interconnected by means of top and bottom longitudinal members and which serve as guiding and actuating devices for vertically reciprocable parts operating on two sides. or columns arranged in alignment with each The shafts other may be provided with left hand and right hand thread in such a manner that every second shaft or column will have left hand thread and that the shafts or columns therebetween will have right hand thread. The said left hand and right hand thread is engaged by corresponding nuts which are interconnected in such a way that like nuts are always driven by one and the same driving shaft. Thus the shafts or columns according to the invention also serve to simplify the drive mechanism, since special means for compensating the axial thrust on the driving shafts can be dispensed with.

Finally, for purposes of effecting a height adjustment, the shaft or column according to this invention may be fitted at its lower end with a suitable device which is coaxial to said shaft or column and does away with any special levelling means on the machine. Again, an adjusting device which is coaxial with the shaft or column may also be provided at the upper end of said shaft or column to permit of regulating the height position of some part supported by it, such as the bearing of a draft or delivery mechanism.

Structural arrangement Referring now to the drawings in detail, Fig. 1 demonstrates the principle of the invention as applied to various vertically reciprocable parts, such as are used in spinning machines. For example, the invention is applicable to the movement of a spindle rail I, a ring rail 2, the thread guide rail 3, or the drawing frame 4 of a ring spinning frame, and one or the other of these parts or several of them may be assumed to be connected to at least one part moving up and down which is not connected to other vertically spaced parts.

According to the present invention, the axis of the guiding device for the vertically movable parts i, 2, 3, and 4 respectivehr coincides with the axis of the actuating mechanisms therefor. Applied to the example illustrated, this means that the guides which are formed by the sleeves 5, 6, 1, and l of the slides 3, HI, II and 12 carrying the movable parts I, 2, 3, and 4 have the same vertical axis as the parts which effect the up and down motion and which, in the example shown in Fig. l, are represented by the non-rotating spindle l3 and the nuts i4, l8, l6 and i1 rotatably mounted thereon.

It is obviously not imperative that the shaft or column 13 is an undivided one, it is .merely necessary that the partsi, 3, and '4 respectively are guided and moved coaxially with regard to each other.

The rotation required to effect the reciprocal movement is imparted upon the nuts i4, l5, l8, and I1 inthe usual way by the shafts l8, I9, 20, and 2| whichare driven by the machine and drive the gears 22, 23, 24, and 25 which mesh with the teeth out into the periphery of said nuts. The gear drive (not shown) of the machine effects an alternate clockwise and counter-clockwise rotational the shafts 18, I3, 23, and 21 whereby the up and down motion is being obtained.

As will be seen, the screw spindle ll itself forms part of the actuating mechanism, and the thread l3 cut into the spindle is preferably a square thread. This form of thread prevents "any jamming as is likely to occur if there are angular or trapezoidal threads.

According to the embodiment of the invention shown in Fig. 2. a plurality of rising and lowering parts I, '2, 3, and 4 are provided which correspond to those parts of Fig. l designated by the same reference numerals. Also in this instance, the guiding and actuating devices are aligned coaxially with each other. More specifically, shaft or column I30. forms a piston rod with pistons 23, 24, 25, and 26 which serve as guiding elements and are cooperating with cylinders 21, 28-, 23 and 30 which simultaneously serve as carriers for the rising and lowering parts I, 2, 3, and 4 or form parts thereof. As driving medium, pressure fluid such as oil or some other liquid medium may be used. By means of a control mechanism (not shown) which may be of any standard type and is governed by the machine, this fluid is forced through ports ll, 32, 33 and 34 or 35, 36, 31, and 38 and through corresponding valves into whichever cylinder chamber is empty, whereby the parts I, 2, 3, and 4 respectively are either raised or lowered.

Uniform guiding and actuating elements for the rising and lowering parts in accordance with the present invention may be fitted at suitable points of the machine frame, but can with great advantage also be used as supports for the machine frame whereby a still greater simplification and cleamess of design is obtained. This is evident from Figs. 3 and 3a showing this feature in connection with a two-sided ring twisting machine (only one half of the transverse section being shown). For the sake of distinctiveness, an arrangement in accordance with the invention. comprising a screw spindle as per Fig. l with two vertically movable parts is shown in Fig. 3, whereas Fig. 3a shows a guiding and actuating arrangement designed as piston rod similar to that of Fig. 2.

As will be clear from Fig. 8, there are two vertical shafts or columns I!" (one only being shown) which are located in one and the same transverse plane and are connected to each other by means of bottom transverse members 3! and top transverse members 43 which bear against respective shoulders or flanges 4i and 42 respectively of the shafts 43'. The simple frame work thus obtained can be multiplied to suit the desired length of the machine and the power available. All transverse members belonging to a machine may be interconnected in longitudinal direction by suitable means such as angle rails 43, at the top, and similar rails or rods 44 at the bottom. The top and bottom transverse and longitudinal members 39, 40 are connected with the shafts or columns I3" by means of nuts 45 and 4 respectively so as to form a substantial machine frame with a main or end frame 41 at either end.

Due, to the fact that all threading is done on the only supports l3" available in the machine. both static and dynamic stresses are favorably distributed over the machine structure which effectively prevents any displacements of the parts relative to one another due to different stresses within the frame.

The arrangement of Fig. 30 substantially corresponds to that of Fig. 3 with the exception that the thread-gear drive is replaced by a pistoncylinder drive as has been described to connection with Fig. 2. Those parts of Fig. 3a which correspond to those of Fig. 3 carry the same reference numerals but with the mix The shafts or columns (only one being shown) are designated 13a.

The columns or shafts l3" and 13a respectively may also be provided with some leveling means, i. e. means for effecting a height adjustment of the machine proper to compensate for any difference in the level on one hand, and means for effecting a height adjustment 01 devices which are carried by the machine, such as drawing or delivering mechanisms, on the other hand. Both types are shown in Figs. 3 and 30,.

To compensate for any differences in the level of the floor carrying the machine, the column or shaft l3 and 13a respectively is fitted with a thread 48, 48 at its lower end which may be the same as that required for the fixing nuts 45, 45, while a spherical cap 49, 49' is screwed unto the shaft or column and is secured in position by means of a lock nut 50, 50. Set according to a spirit level during the assembly, the two spherical caps 49, 49 permitof varying the level of the machine should this prove to be necessary in service from whatever cause such as settling of the floor.

A similar arrangement can be made at the upper end of the column or shaft I 3', Ba respectively to regulate the height of working parts belonging to the machine. For example, Figs. 3, 3a diagrammatically show the delivery mechanism 5|, 5| of a twisting frame, the bearing 52, 52 of which may be adjusted in height by means of the nut 54, 54' which can be raised on the thread 53, 53 of the shaft or column 13', I3a' respectively. The lock nut 55, 55 will secure the height adjustment made. Also in this instance, the thread 53, 53 may be the same as that in the fixing nuts 46, 46.

Instead of uniting two adjacent columns or shafts l3" and i311 respectively in one and the same transverse plane by means of transverse and longitudinal members so as to form a substantial machine structure, it is also possible to provide a machine structure comprising only a single row of columns with double-sided operations. This is achieved by arranging a number of vertical columns or shafts l3b in line and connecting them by mean of top and bottom longitudinal members. In such an arrangement, said columns or shafts serve to guide and drive vertically movable parts working on two sides. A machine of this type is shown in Figs. 4, 5, and 5a.

Located in the longitudinal direction of the machine is a row of columns or shafts which may be designed either as shown in Fig. l (as for the rail l) or in Fig. 2 (as for the rail 2). Of course, a mixed combination of shafts or columns is also feasible.

Each column out of a row of such columns may be fitted with a compound base 56 which is connected to the two adjacent ones, for example, by means of the longitudinal rods 5'1, 57, whereas the upper parts of said columns are connected to one another by means of a continuous member or a rail 58 which may at the same time serve as a bearing for a working unit 53. End frames Bil, of which the one incorporates the driving gear as usual, close the machine at each end.

In such an instance, the working parts moving up and down, such as the spindle rail I and the ring rail 2, are arranged symmetrically to the vertical axis of the column and are fitted to suitably designed guiding and actuating devices 5, It?) and 24", 28" respectively, and it will be evident that due to the carrying columns being designed according to the invention, the entire machine requires considerably less floor space than any other type known heretofore.

If machines comprising the single row arrange- .ment'of columns according to Fig. 4 are equipped with columns of the type shown in Fig. 1 (spindle rail 1 in Fig. 4), it is also possible for the end thrust to which the driving shafts l8 or I9", 20', 2| are subjected when lifting and lowering, to be compensated by designing the columns or the actuating mechanisms accordingly. To this end, the invention suggests that the columns or shafts I317, I317 arranged in line be provided with alternating left hand and right hand thread I30 and M11 respectively. This thread is engaged bycorrespondingly threaded nuts 14a, [41), the arrangement being such that like. nuts are driven by the same shaft. Thus, with reference to Fig. 5, shaft l8 drives all nuts Ma, and shaft l8" drives all nuts I 4b. The driving connection between shaft l8 and the nuts l4a is effected by gears 22' connected to shaft l8 and engaging the nuts I 4a. Similarly, the shaft l8" has connected thereto gears 22" meshing with the nuts Mb.

The arrangement just described may correspondingly be applied to machines comprising a double row of columns, in which instance one row has left hand thread, while the other row has right hand thread.
